Perl DateTime nanoseconds always 0

Question

How i can get nanosecond from DateTime in Perl?

I try

say DateTime->from_epoch(epoch => time)->nanosecond; # 0
say DateTime->from_epoch(epoch => time)->strftime('%9N'); # 0

Does this answer your question? [How to get system time in nano seconds in Perl?](https://stackoverflow.com/questions/26032541/how-to-get-system-time-in-nano-seconds-in-perl) — Rudedog, Aug 27 '21 at 15:55

time returns the number of (whole) seconds since the start of the unix epoch. Time::HiRes provides a version of time with better resolution.

Note that Time::HiRes::time only gives answers in steps of 2**-22 seconds or 0.24µs. (For a full explanation, see https://stackoverflow.com/a/66487325/5781773)
